MULTIPLANE FLYING-MACHINE.

To all whom it may concern:

Be it known that I, GIANNI CA'PRONI, engineer, subject of the Kingdom of Italy, residing at Milan, Via Durini 24, Italy, have invented certain new and useful Improvements in and Relating to Multiplane Flying-Machines, of which the following is a specification.

, This invention relates to large and power ful flying machines.

The object of the invention is to construct an improved type of flying machine having a very extensive supporting area and capaisle of carrying heavy loads for long distances and adapted to keep afloat on water when necessary.

The invention consists in an improved aeroplane comprising a plurality of multiplane groups each longitudinally and vertically framed together; a plurality of girder members, symmetrically positioned relatively to the longitudinal axis of the ma- .chine, and extending parallel thereto through the multiplane groups, to the longitudinal and vertical framings of which the said girder members are connected; a car exten ing beneath the lower planes of each group, and the'provision of stay cables by which the car is respectively suspended from and attached to the main girder members and the frameworks of the multiplane groups.

The accompanying drawing represents by .way of example a constructional form of the invention.

Figure 1 is a side elevation.

Fig. 2 is a partial front elevation, and

Fig. 3 is a plan view.

Like numerals represent like throughout the drawing.

The improved flying machine as illustrated in the drawing, Figs. 1 and 2, is constructed with three multiplane roups arranged in front, intermediate an rear positions respectively and each constituted of planes -1-, -2, 3:-, uprights and stay-cables -5-- joined and combined parts together in the manner usually adopted by aeroplane constructors. The plane groups are connected to each other y means of girders or fuselages -6, --7-- which extend through the groups and preferably are joined to the central planes of each group by means of bolts, stlrrups, rlvets and the like, said means of junction being applied longitudinally and vertically both as re- Specification of Letters Patent.

Application filed February 13, 1920. Serial No. 358,445.

gards the girder or fuselage and the plane group framing, and in accordance with the method disclosed in some of my previous patents.

Between the girders or fuselages -6-, -7- and beneath the lower planes 3, is mounted a torpedo-shaped car --8-.

Said car is joined to the middle uprights 4 (which may be prolonged downward for that purpose) by means of bolts, stirrups' and the like.

Stay wires -9- joining suitable points of sald car with points of the fuselages 67- are provided to make the connection as safe as possible.

The dotted triangle in Fig. 2 is intended to represent the projection of a plurality of further stay-wires or cables joining to gether the three structures -6- -7- -8.-.

The side floats-.15 are mounted beneath the lowest plane of the central group to facilitate alightin on water and main taining the balance 0% the machine when in operation.

The fuselages or girders -6-, -7 are constructed with cock pits l0-- atboth ends, wherein the motor engines are mounted, while nacelles 11 or the like, which are located centrally with both front and rear plane groups are provided with cock pits --10 for the reception of additional motor engines, each nacelle'-11-- or the like being attached to the uprights 13- through the side members -12-- which are also joined to the longitudinals of the middle planes.

The arrangement of the engines per se forms no part of this invention, but is included in my copending application of the same date.

In flying machines constructed according to this invention no center girder or fuselage is used but it is to be understood that .intermediate girders or fuselages may be nally disposed girders connecting the intermediate planes of the multiplane groups together; a car beneath the lower planes of the multiplane groups, and stay cables for attaching the car to and suspending it from the girders and multiplane groups.

2. A flying machine as claimed in claim 1 wherein side floats are connected to the under side of the lower plane of the interinediate multiplane group on opposite sides of the car.

3. A flying machine as claimed in claim 1 memes wherein the uprights and the intermediate inultiplane groups are extended and connected with the sides of the car.

4. An aircraft including a plurality of multiplane groups, girders connecting the groups in longitudinal alinement, a car extending beneath the multiplane groups and stay cables for rigidly connecting the car, 20

girders and groups together.

In testimony whereof I afiix my signature.
